Имя (Name)

sd_bus_message_seal - Prepare a D-Bus message for transmission

Синопсис (Synopsis)

#include <systemd/sd-bus.h>

int sd_bus_message_seal(sd_bus_message *m, uint64_t cookie, uint64_t timeout_usec);


Описание (Description)

sd_bus_message_seal() finishes the message m and prepares it for
       transmission using sd_bus_send(3).  cookie specifies the
       identifier used to match the message reply to its corresponding
       request.  timeout_usec specifies the maximum time in microseconds
       to wait for a reply to arrive.

Note that in most scenarios, it's not necessary to call this function directly. sd_bus_call(3), sd_bus_call_async(3) and sd_bus_send(3) will seal any given messages if they have not been sealed yet.


Возвращаемое значение (Return value)

On success, this function returns a non-negative integer. On
       failure, it returns a negative errno-style error code.

Errors Returned errors may indicate the following problems:

-EINVAL The m parameter is NULL.

-EBADMSG The D-Bus message m has open containers.

-ENOMSG The D-Bus message m is a reply but its type signature does not match the return type signature of its corresponding member in the object vtable.


Примечание (Note)

These APIs are implemented as a shared library, which can be
       compiled and linked to with the libsystemd pkg-config(1) file.
